Use different combinations of search terms and evaluate your results each time. How do the results change?
After performing a search, look for a tool that lets you "refine" or "filter" your results. Try filtering by:
Tip 1: Combine the boolean operators AND and OR for a very specific search query. You can also use NOT to exclude terms.
ethics AND (biometrics OR behaviometrics)
Tip 2: Use an asterisk to truncate a word and search for variants of a word. For example, you can search for both ethics and ethical with one search term:
ethic*
Tip 3: Combine all of these suggestions and analyze the results you get.
